By default, WLAN uses theIEEE802.11a/b/g standard technology for WLAN
connectivity. The standard includes the Wired Equivalent Privacy (WEP) encryption
method, which is a security protocol and WiFi Protected Access.
To use IEEE802.11b or IEEE802.11g WLAN connectivity standard only, select
them from the Mode field drop-down box.
Configuring the WLAN connection
You can configure your computer to connect to a WLAN using one of the
following ways:
❑without an access point device (ad-hoc)
❑with an access point device
An ad-hoc network is a network in which a local network is created only by the
wireless devices themselves, with no other central controller or access point
device. Each device communicates directly with other devices in the network.
For example, you can set up an ad-hoc network easily at home to communicate
between two computers.
A computer communicating with an access point device is configured as part of
an infrastructure network. An infrastructure network is a network that extends an
existing wired local network to wireless devices by providing an Access Point,
✍Wireless LAN devices using the IEEE802.11a standard and the ones using the
IEEE802.11b or g standard cannot communicate because the frequencies are
different. Wireless LAN devices using the IEEE802.11g standard can only
communicate with a device using the IEEE802.11b/g standard, not with the
IEEE802.11a standard.
✍IEEE802.11a: The standard speed is 54 Mbps, or about 5 times faster than a Wireless
LAN device using the IEEE802.11b standard. The IEEE802.11a connection is only
available on certain computer models.
✍IEEE802.11b: The standard speed is 11 Mbps, or about 30 to 100 times faster than a
standard dial up.
✍IEEE802.11g: The standard speed is 54 Mbps, or about 5 times faster than a Wireless
LAN device using the IEEE802.11b standard.

Answers to Frequently Asked Questions
❑General
Question: What is the SmartWi Connection Utility?
Answer: SWCU is a wireless connection utility application that is designed
to switch and manage wireless connection modes between Bluetooth,
802.11, and Cingular GPRS/EDGE.
Question: Can I connect to two separate types of wireless connections
simultaneously (for example, GPRS and 802.11b/g)?
Answer: No. Connections are mutually exclusive, with the exception of
Bluetooth which will run concurrently with other wireless connections.
Bluetooth can be switched on and off via the software without causing
interference to the current connection (for example, GPRS or 802.11b/g).
The hardware indicator/switch for the wireless devices is located at the front
panel on the left side.
❑SWCU Operation
Question: Why do I get a VAIO Assistant prompt when launching WLAN?
Answer: If there is not any WLAN profile configured previously (this is the
first time using WLAN), the VAIO Assistant will be launched automatically,
or the VAIO Wireless Help Utility loads when it detects a failure in
interfacing with the driver. To remedy the problem, follow the suggestions
from the assist help section.
Question: I clicked the “Show All Prompts” button for the Reset all
messages feature, but nothing seemed to happen. What happened when I
clicked this button?
Answer: Clicking the Show All Prompts button for the Reset all messages
feature activates all the prompts (not options) that request the “Don’t ask me
again” action. Normally, when notifications appear from yes/no prompts you
can select if you do not want to be asked again for the notifications by
checking the “Don’t ask me again” check box. The “Reset all messages”
feature provides a way to clear all the checkboxes from all the prompts
simultaneously. As a result, the prompts will display again.
Question: I clicked on the SmartWi minimize option and noticed the
minimized icon was not in the taskbar. Where is the minimized application
Answers to Frequently Asked Questions
27
and how do I bring back the application to the desktop?
Answer: The SmartWi application was minimized into the Task-tray, which
shows the “SWCU” icon and not into the “Taskbar”. Depending on the type
of connection and combination, if any, the SWCU icon will reflect the
current connection. For example, if the SmartWi connects simultaneously
with the Bluetooth device, the icon will reflect the connection type with a
Bluetooth emblem. Switching on and off the Bluetooth option does not
interfere with WiFi or WWAN connection.
To bring forward the SmartWi application to the desktop, click the SmartWi
icon from the task-tray once (see the following illustration) or navigate to
Start --> All Programs --> SmartWi Connection Utility, and then click the
SmartWi Connection Utility icon.
Question: Why do I not have an option to delete WLAN profiles from the
SmartWi WLAN profiles list in the Advanced Settings window?
Answer: Profiles can be managed and edited via SmartWi, but cannot be
deleted. Profiles can be deleted from Windows Wireless Network
Connection Properties or the Intel ProSet Wireless that displays when
clicking Configure WLAN on the SmartWi WLAN Settings dialog box.
Question: I noticed that if I open a WLAN connection from SmartWi,
sometimes the WLAN profile in Windows Wireless Network Connection
window shows “Not connected”, but actually the connection is established.
Answer: Under the Windows Wireless Network Connection window, click
on the “Refresh network list” located under “Network Tasks”. This should
refresh Windows and provide an accurate overview of wireless status. If this
is not fixed the problem, then close the Windows Wireless Network
Connection window and re-launch it from Windows network connections.
❑Cingular Connection Manager (CCM)
Question: What does it mean to “Restore” from the tool help bubble?
Answer: Clicking the “mini bar” option once, reduces the full details to a
Minimized WWAN and Bluetooth connection icon
VAIO® Computer Wireless Information
28
“mini bar”. Click the “Restore” option to return to full details view.
Question: Why does the “Connection Log” not sort when clicking on the
columns title bar?
Answer: This feature will be available in future versions. Sorting by type,
technology, date/time, duration total bytes and description should be
available in future versions.
Question: Why do I see “Device not detected” in the Cingular Connection
Manager details window?
Answer: This is most likely to occur while switching from WWAN to
launching CCM. There is a slight timing degradation that occurs while
making the switch which causes this status. Turn off the WWAN and then
reconnect the WWAN to fix the problem.
Question: CCM sometimes fails to respond after resuming from Suspend
mode. What could be the problem?
Answer: If the “General” tab under the Edit Profile screen for GSM is left
open, this can often keep CCM from reopening upon resuming from suspend
mode. Make certain the “Edit Profile” screen has been closed after making
any changes. A reboot should correct the problem.
Question: When I try to connect through Cingular GPRS network, the
Connect/Disconnect button is greyed out, and there is no connection
available.
Answer: Click on the “Connect Using “tab in CCM, and check one of the
connection types from the drop down menu. Close out of CCM and reboot.
Question: I noticed an option to create a CSD Accelerated/Non-Accelerated
network profile. What is this?
Answer: CSD is Circuit Data Network. This is an older technology with
lower throughput which has been phased out. We recommend that
EDGE/GPRS Acelerated/NonAcelerated profile options be used instead.
❑SMS
Question: What does “Load” do and why does it not prompt for options or
input?
Answer: The SMS help file indicates this is useful in case of accidental
deletion of messages. The “Load” feature would be a way to recover the
Answers to Frequently Asked Questions
29
deleted messages, however, this option provides no notification that the task
completed successfully.
Question: What does “Save” do and why does it not prompt for options or
input?
Answer: The help file indicates this keeps the current state of all folders,
except the inbox. However, no notification is sent indicating the “Save”
completed.
Question: I copied a message to the “Outbox”. Why does it not prompt to
enter the recipient?
Answer: Although you can move or copy a message from one folder to
another, including the “Outbox”, the message must have a recipient before
the message can be sent. If the message is copied and/or moved to the
“Outbox”, the message still will not have a recipient, thus leaving the
message unable to be sent. This would be considered the same as a the
“Forward message” feature. The message would remain in the “Outbox”
indefinitely until a destination or destinations are provided. For working
around this, we recommend double-clicking on the message, enter a
recipient, and then click “Send”.
Question: I created an SMS message, but am not connected to GRPS. How
is it possible that the message can be sent?
Answer: Sending SMS does not need a GPRS data connection. As long as it
detects and attaches to the Cingular network, it will able to send SMS.
Question: What is, and what does the function button “Update Address
Book with Phone Book Contents” do?
Answer: When the SIM is installed, it contains a built-in phone book, which
when using this feature, allows the contents of the phone book to be
incorporated into the address book.
Question: Why I am not alerted of transferring the contents of phone book
to the address book?
Answer: This is a feature that is still under development. A request for
further study to be conducted with this option has been applied.
Question: When I select a message from a folder, and then scroll right, the
all previously existing messages appear to be gone if I scroll back to the
VAIO® Computer Wireless Information
30
original folder position.
Answer: Click out of the folder, and then back in to refresh the screen.
Question: I clicked on the Cingular Connection Manager minimize button
and noticed that the CCM icon was not in the taskbar. Where is the minimize
icon and how do I bring forth the application to the desktop?
Answer: The CCM minimizes into the Task-tray, which is represented by
the “Cingular” trademark cross icon and not into the “Taskbar” (see the
Cingular logo illustration below). Depending on the strength of the GPRS
signal, the trademark will reflect this with a degree of graduations. In other
words, if the signal strength synchronizes to 3 bars (see the Task-tray
illustration below), the Cingular trademark cross will show approximately
half of trademark jackman in the task tray. If the signal strength is one bar,
the trademark jackman will appear to show a bottom portion of the
trademark jackman. If the signal strength is at five bars, the entire Cingular
trademark jackman will be fully indicated.
To bring forth the CCM to the desktop, click the Cingular trademark icon in
the task-tray or right-click the Cingular trademark cross and select “Show”.
❑GPRS Network
Question: Why do I see a network connection speed rate of 214.4 Kbs, but
when I try to access a website that requires a minimum of 128 Kbs, I am told
that I do not have the required minimum rate.
Answer: The network speed indicator provides the capacity of the wireless
device is 214.4 Kbs but the actual speed depends on network throughput. To
work around this, try to change the network settings to optimize the

GPRS/EDGE value. This is done by accessing CCM --> Tools -->
Settings… --> Advanced Networking, and then selecting “Optimized
GPRS/EDGE value” option form the RWIN variables window.
Question: I am experiencing dropped connections, slowness, and other
difficulties while attempting to stream video over the Cingular GPRS
connection. What could be the problem?
Answer: Bandwidth over the Cingular GPRS network is somewhat
restricted as compared to wired or 802.11x wireless connection types. Due to
the demanding nature of streaming audio/video, it is not recommended that
GPRS be used for either streaming video, or very large data downloads.
Question: I am experiencing difficulty reconnecting to my web browser
when switching from the Cingular GPRS network to a WLAN connection.
What could be the problem?
Answer: The network behind the WLAN’s Access Point may be set up to
use a proxy server. If this is the case, proxy settings entered for Internet
Explorer over WLAN may prevent IE from connecting over a GPRS link.
To allow web browsing from either connection type:
1Correctly configure IE proxy settings for use over the WLAN
connection. Then, open the Cingular Connection Manager and right-
click the “GSM” tab. Select “profiles” and then click on the “Edit”
button.
2Under the “General” tab, make certain that the “Disable IE’s manual
proxy settings on connect” checkbox has been enabled. Close the “Edit”
screen and then close and reopen Internet Explorer. Remember to close
and reopen IE each time you switch connection types in order to refresh
proxy settings within Internet Explorer.
3If you are still having trouble, contact your network administrator to
assist in obtaining the proxy settings.
Question: I am seeing a message in Windows taskbar stating; “GPRS a
Network Cable is Unplugged”. What does this mean?
Answer: Typically, this message appears if your VAIO PC is connected to
the Cingular GPRS network and is allowed to go into hibernation. Upon
resuming, Cingular has terminated the connection. However, Windows
information has not yet been updated to recognize this change and is
unaware that your GPRS connection does not require a cable. You may
VAIO® Computer Wireless Information
32
either re-connect to Cingular, or simply cancel out of the message.
Question: Downloads sometimes appear to be slow when connecting to the
Internet via CCM. What type of download speeds should I expect?
Answer: Since CCM operates over a cellular network and is subject to the
same issues/conditions as cellular connections, bandwidth may vary greatly.
Common download speeds ranging from 18~64Kbps are possible with
30~36Kbps rates as typical. However, these are only estimates and your
actual experience will likely vary depending upon a number of
environmental factors.
Question: What is meant by “RWIN” from the CCM Tools settings
advanced networking section?
Answer: The TCP Receive Window size is the amount of ‘receive’ data (in
bytes) that can be buffered at one time on a connection. RWIN (TCP Receive
Window) can be changed using the method of setting up the variables to
optimize TCP. We recommend that this setting not be changed unless you are
an expert or you have explicit instructions from your network administrator.
❑Sonic Stage/Music Store
Question: I am unable to stream audio from some web sites such as
Winamp©, Shoutcast©, etc. using Sonic Stage? Why is this the case?
Answer: Many of these web sites use proprietary players and use encoding
formats that are not supported by other players. You can download one of
these players if you wish, or try streaming from Sony Connect™ Music
Store using Sonic Stage.
Question: Sonic stage appears to lock up indefinitely (displays a spinning
‘LOADING’ logo) when attempting selecting “Radio Connect” (streaming)
from Sony Connect™ site.
Answer: This is related to the issue of streaming audio over low bandwidth
connections as referenced above under “GPRS Networking”. Connecting to
Music Store over a wired or broadband connection will usually resolve this
issue.
✍Changing the settings for this value also has an effect when using WLAN
device or any device that depends on TCP connection.
